ConnieT,
I had a non healing peg tube site (stoma) after the peg tube was removed after 5 or 6 years. They closed the stoma site off with stitches from inside the stomach, and maybe something else. Turns out I have Barrettts Esphogus from the biopsy, but the peg tube site did heal, and closed, and had no problems since, at least with the tube site.
Good luck with everything!
